Bug#667599: dolfin-dev: fails to upgrade from squeeze - apt does not find an upgrade path

[David Kalnischkies]

Hello hdf5-maintainers!


In bug #667599 we have a report from piuparts that APT is unable to
upgrade delfin-dev from squeeze to wheezy.

The problem is that APT has to decide in this process if it wants to
have libhdf5-1.8 (= libhdf5-openmpi-1.8.4) or libhdf5-openmpi-7
installed and finally decides against libhdf5-openmpi-7.

Removing conflict(+provides+replaces) for libhdf5-1.8, libhdf5-1.8.4
and libhdf5-openmpi-1.8.4 obviously prevents APT from having to
decide between the two, so you might guess what i want to ask:
Could you hint me at why these conflicts are in place?

A quick check regarding the filelist suggests that the "old"-style 1.8.*
versions provided a libhdf5.so.6 library while the new one provides
libhdf5.so.7 so I wonder if these Provides are correct at all.
At least there seem to be no file conflicts between those packages or
did I miss the obvious?

(leaving assigned to dolfin as this is just a guess)


Thanks in advance and best regards
